I'm all out of invites by now, sorry.
This is fascinating as I discovered exactly the same thing this week (sadly after applying loads of javascript to swap retina images).

I found that a 30 jpeg at retina size generally looks better than a scaled 80 and is smaller.

Plus you can zoom in on any Mac, not just an iPad (something I do all the time).
Daemon by Daniel Suarez is a book every programmer will love
Curious if we apply it further whether or not it works. At which point does the pattern break-down? 4x and Q20? 8x and Q10? etc
If anyone else has an invite, I wouldn't mind trying this out
Honestly, I did not notice any JPEG artifacts on any of those images, so I don't think it's that obvious yet.
It looks great.

I think you should state clearly before the "Register" step / button that it's only available in the US at the moment. I looked around, I liked the idea, I wanted to see more so I signed up and ended up having to chose a location in the States (which I can't, obviously, being in Europe).

I've seen this handled on eBay by some by including a "safe" product which is listed as the item for sale, and "giving" away the item that's excluded from being resold. Basically the buyer and seller have a full understanding of what the transaction is about, but selling the non-regulated item seems to be enough to circumvent the intent of the law.
Thanks for the suggestions! Nit picking is good ;-) I will revise the résumé and include your comments.

At first I had detailed the projects I worked on in Accenture, but they ended up taking too much space. I'll try to improve on that.

Increasing productivity is the main point of Information Technology. Of course, everything you can do with a computer, you could do with file cabinets and multiplication tables, but the only goal of information technology is to increasing the speed at which you can process your information, ie. increasing the productivity of your users. That's why sales pitch put this forward. Yes, sometimes it's bullshit, and yet, sometimes it's not. Overall, productivity has increased since 1950, so that must have come out of somewhere...
This test was done COMPLETELY WRONG.

Look at the details on the jpeg settings from the image itself.

Subsampling is turned off for some and on for others, which gives the target size far fewer bytes to work with.

This is a common problem with photoshop users, they use the highest settings which turns off subsampling but then reduce the filesize allotment which gives it less room to work with. You get better results if you have a target filesize by turning off subsampling first, which photoshop does not do by default until you drop the quality target very low.

This entire test has to be redone.

Use SUBSAMPLING OFF and PROGRESSIVE ON for all (jpeg) images for the web.

(and do not use default photoshop settings ever for web images)

ps. every time you save a file or image in adobe products it embeds a hidden fingerprint (beyond exif) that identifies your specific install - so not only does it add extra file size, every image you post can be traced on the web - use jpegtran or jpegoptim to strip it
It should not.

An outdated computer/browsers sucks at resizing jpegs. A two year old high end Android smartphone too.

Minimizing HTTP requests, avoiding FOUC, using only one version of JQuery (or, even better, none), using CSS sprites... there are countless optimisations which are more important and seldom used.

Retina is a buzzword and a buzzword resolution. If you target the 0.1% rich hipsters, yeah, it's important. If you've real users browsing in 1024x768 on a four year old laptop and a 2Mbps broadband, it's not.

When Amazon'll use Retina img, that's when it'll be a standard practice.
The claims that productivity maxes out at 40 hours are extremely weak empirically.

http://www.overcomingbias.com/2011/12/work-hour-skepticism.h...

The most current evidence I've seen suggests 60 hours is optimal for productivity, not 40.

http://www.overcomingbias.com/2011/12/construction-peak-60hr...

[edit: let me clarify that there is basically no data on knowledge workers. Anyone making claims about them, whether the magic # is 40 or 60 hours, is extrapolating from manufacturing and/or construction work.]
I assume you've learned this from somewhere in the bowels of the photoshop documentation or years of domain knowledge? I ask because as a photoshop user of 5 years I've always wanted to learn a LOT more about the nitty gritty details (I am on hackernews :P) of what I was exporting but I didn't find a solid end-all be-all resource. Any ideas where I can find one?
The source for the manual is still up, and is quite readable despite the few style annotations:

http://code.google.com/p/chibi-scheme/source/browse/doc/chib...

Note: I don't have access to the original manual link either, so I can't confirm that it's exactly the same document. It describes the language in details.
People in China, like everywhere else, want people held accountable for their actions. If government won't do it, they will do it themselves if they can.

I read that people from the provinces experiencing an injustice can go to Beijing to seek justice. But if too many people from a province do that, the province gets in trouble. So the provinces actually send agents to Beijing to kidnap their own people to keep them quiet.

There is no reliable system of courts and appeals and justices that will rule against even the powerful when the cause is just. That simply encourages more injustice.

I think this is China's biggest challenge. It won't change until the rights of the individual are recognized.
Law has much faster changes than programming. In programming you can use 2 year old ideas and be fine, in law no so much. A single case before the supreme court can completely change what's legal. And just about every bill changes something significant for someone.

Ditto doctors, you are required to stay up to date, where programmers can come back after 10 years and learn on the job doctors need to pass a "Maintenance of Certification Exam" or break the law.

PS: Programmers do need to keep learning, but it's no where near as time consuming.
Mike Lee of Appsterdam, had a talk at at AppsWorld, where he said pretty much the same:

Working at Apple, he had heard the rumors that if you went into an elevator with Steve Jobs, you had to explain what you did and why you were doing it before he left and as such – even though he didn't believe in the rumor – he tried to explain all he did in only 60 seconds.

This is what he answered, when asked for his currently 60-second-speech: "I'm making educational games for kids. […] It's just enough to make you curious and want to have a conversation. […] If your 60 seconds-talk is an attempt to try to cramp as much shit into 60 seconds as you can, you're doing it wrong."

I can only recommend listening to the whole 30-minutes: http://www.apps-world.net/europe/images/stories/audio/dev-d1...
Imagine if all those hours were spent on something constructive.
I think it's pretty easy to get flamed on IRC; pick a channel and then pick an opinion that differs from the majority. I've been told I was stupid and irrational for preferring the wrong code editor before. It's admittedly infuriating when supposed adults act and argue like children, but I guess it's not a big deal in the long run.
I also follow Ricardo Cerqueira... and Jeff Dean, Brad Fitzpatrick and Linus Torvalds. It's like a small private space.
He's comparing the experience of being an open source project under ASF to that of being a free software advocate for gnu.org. This is when he mentions loving the community more than the code.
Only that you made a horrible mistake.
Thank you Jason, what a super list. And as a side effect, what a super compliment to those that work with you.
Even that being the case, the higher resolution image would need to have awful artifacting to be worse than the lower res image on a high res display. Scaling up a low-res image in the browser will always make it look fuzzy, you'd need to apply filters to sharpen it up, and you'd still definitely lose detail lost in the original shrink.

Command-W: Close tab

Command-Shift-Enter (In omnibox): Open in new tab
Delete or Command-[: Back

Selecting and activating links with the keyboard:

Command-F: Show and focus find bar
Enter or Command-G: Find next
Shift-Enter or Command-Shift-G: Find previous
Control-Enter: Activate highlighted link

This is limited, though; there is no way to open a link in a new tab, and find starts from the top of the page (bug?).

Personally, I find it more efficient and ergonomic to scroll and select links with my MBP's trackpad. Scrolling is especially fluid with two-finger smooth scrolling. Gestures and the changes to scrolling have allowed me to forgive a lot of weirdness about Lion and Mountain Lion.

FWIW, in case you don't have a retina display, zooming in your browser works just as well to make the difference in quality visible.
I rarely use photoshop myself - I learned it from having to support photoshop users and solve why the images they upload to the CMS system were so massive, ie. 400k for a 600x600 photo

What we did for the non-tech people was simply tell them to always use setting #6 on photoshop and use the progressive setting. Two steps seemed the most they could handle.

http://i.imgur.com/vct3D.png (best one-shot photoshop settings for web jpegs)

I had to go into photoshop and save the same image repeatedly under all the different settings and then examine the resulting jpeg under different tools to see exactly what it was doing.

It also doesn't help that photoshop bloats jpegs by adding hidden adobe meta to every jpeg (beyond and different from exif).

Here is a technical analysis someone did on the photoshop settings:

The studies referenced in the article you linked refer to the construction industry, not knowledge workers. I would expect anyone producing widgets or physically fabricating things would continue to produce more simply by spending more hours on the job. The question relevant in the original article, and to most of the HN readership, is whether knowledge workers (programmers, engineers, etc.) can get more done by spending more hours at work. I tend to think not, past a certain point, but I'm not entirely where that point is. It certainly depends on what you're doing, culture, work/life balance, hard focus capability and many other factors.
The cost of doing it always is primarily in extra memory used on the client, while the quality loss from poor client downsizers should not be too bad, particularly if you target 2x resolution.

IME the best bandwidth optimization is an adblocker :)
Don't know am I too optimistic, but I think that R7RS large will be great success.
I hope rest of the community share same enthusiasm.

I don't think observations from construction projects are going to relate 1:1 to knowledge workers and professions that rely mostly on (creative) mental labour.
"This Site Totally Doesn't Work Without JavaScript."

Pure CSS my arse.
I also would be interested in a blog post about this. Seems to me (and some other commentators) on this thread, that very often there's an "infinite" amount of work to do, and I don't see how that squares with "we pay you for results".

A team I was on a few years ago did scrum (poorly). We had a list of tickets the product owner wanted done for the sprint. Except, more often than not, additional tickets would be added into the sprint (Either because us engineers found dependencies or because of additional bug requests).

Scrum doctrine says that you now have a broken sprint, and all bets are off. Did it matter to management? Nope.

This was a large Rails project (about 7 full time developers for a year+). It's possible it's different when you're working on many small projects.

I guess my worry about ROWE is situations where the result is, "Implementing all your tickets on your plate" and worries about what happens in environments where tickets get added to your plate such that the number of your tickets on Thursday == the number of your tickets on Tuesday. (Even though you implemented 6 tickets between now and then). I would certainly be interested in any comments/information/thought you have on a situation like that.
Observing myself, it's closer to 20, unless I've done it before and know exactly what to do. If I push harder, I do a lot more rework. I'm not counting background thinking, of course.

I think it's very dependent on the nature of the work.
Which is a fair point, but it depends who you're targeting: if affluent users are more likely to have high-DPI devices (iPad 3, most smartphones, high-end MacBooks), and they are, then you're going to have to make your site 'retina-ready.' And it's a mistake to thing this is just a young, tech-savvy issue. How many older people are buying iPads? Do you think they'll notice, subconsciously or not, if your site looks a bit crappy?

I have a hard time believing it would be a significant issue to do a 2x image resize, especially if you provide exact image dimensions in your img tag to start with to avoid the renderer having to wait until the image has downloaded to layout the page properly. In any case, I think someone should do some benchmarks to see what kind of an issue it is in practice.

Either way, it's not a bad thing to be forward thinking with design. The amount of 'retina' devices in the world is growing exponentially. At the moment, it's largely an Apple problem, but with high DPI panels now on the market it'll soon be industry-wide.
Is the conclusion wrong?

I work in the same place as Jonathan, and have found working in a results only work environment to be an extreme step up. I started after the transition, and it was a very obliviously different environment than anywhere else we work.

The way we work is that we have very focused week or month or quarterly results we are responsible for, and we have a very transparent way of seeing who needs to do what and what is getting done. Beyond that, it's a big part of our culture not to be negative is someone chooses to work different hours or out of the office. It's their results to complete, and they know how they work most effectively.

You've got a bunch of stuff up on our blog about ROWE as well: http://highgroove.com/tags/rowe
Can you write a blog article with this information, please?

I would be very happy to see a few examples of photograph compressed with the OP method and your method.
Great point. I use Fireworks instead, especially for PNGs. Fw let's you use PNG8, and let's you set the way the transparency is rendered (alpha or index). Large PNG files produced by Photoshop's Save for Web dialog are two to three ones the size of the PNGs I generate w Fireworks.
Kayak takes on the big dogs
Very true. We have little good information on this topic, and the original article is wrong - we don't have good evidence that 40 hours is a universal cap.

Most of the data supporting 40 hours/week applies to manufacturing and construction, and is old. Contemporary data (of which there is very little) suggests 60, and again problems of comparing knowledge workers to construction arise.

If someone has good data, I'd love to see it. Until then, stop citing 40 hours/week as peak productivity.
Just tried this myself with a couple of 8.5MB MP3 files. One appeared on the second machine in about a minute, the other in about a minute 30.

Practical steps for launching a web site on your own?
I've been working on a life organizing site for the past 2 or 3 years now and I'm finally in a position to launch it. However I'm having a hard time coming up with some practical steps that I can do every day to increase its exposure. Marketing isn't my strong suit or even an interest but I know its necessary. I've tried to submit it to the social sites but it seems to get buried in the noise too fast.

I know there are a lot of things that need to be done but its difficult to focus on a strategy when you arent sure where to begin. Any advice would be appreciated.

Truly amazing. What's even more amazing is how ancient the technology inside one of mankind's most incredible inventions looks compared to what we know today.

It reminds me of a visit to one of Israel's Air Force bases where I got to see the F-16's up close. I couldn't believe it when we were told that pilots upon receiving coordinates, had to open up a notebook beside them and actually look it up to know where to go because their navigation system was so old. The F-16I had a lot of improvements in this area that no longer required manual lookup by the pilot.
No, arch doesn't have anything remotely as use flags. But is 'gentoo-like' in that they serve upstream vanilla, without modifcations. I still prefer Gentoo's use flags and tolerating the suckage that sometimes ocurrs when an emerge fails.

Someone should make a way to sharing ebuilds with the same useflags and CFLAGS(or at least compatible CFLAGS) so users could opt-in and 'crowdsource' the binary generation, as I feel gentoo with binary packages would be the best distro ever (I am aware portage supports binary files, it is just prohibitevly expensive to support all configurations.

Last time I checked Europe was not one country. The business environment in, say, the UK is very much different to that in, say, Germany. It's hard to take articles seriously that speak so broadly and vaguely about such a diverse continent.

Give up trying to measure people against some standard yardstick. It doesn't work in school, it doesn't work at work. People have a complex set of inter-relating competencies, and managing them is challenging work, not an exercise in stack ranking them by some index. Don't be lazy.
AeroFS looks cool but I'm not too keen on having to run Java just to run AeroFS given that I had disabled Java on MacOS due to the recent exploits.
Thanks for that tip. I disabled the limiting now and it sped up from 11:42 minutes to 01:40 minutes! Now Dropbox is only x12.5 slower than AeroFS.

The real solution, of course, would be for Dropbox to transfer the file over the LAN immediately before waiting for it to be uploaded to the Dropbox servers.
Same story for me. Used Pentadactyl until it started causing some performance issues. Now on Vimperator and my fingers couldn't be happier. I guess I didn't really need all the Vim-ness of Pentadactyl.
Ha. Funny.
FWIW, France has a lower proportion of unionized workforce than the US, and a lot lower than the UK in the public sector. It's more about cultural differences than any single thing like unions.
With this comment, I lost any faith in this idea as it's clear this is not about both sides deriving value in the process. In your scheme, startup "founders" or really wantrapreneurs get to try out half-baked ideas by giving away worthless equity to folks that are ultimately being duped while idea guys ultimately talk about their MVP and pivots and other bs that people who fancy themselves as startup founders think they should talk about.

On a related note, the "founders" participating in sites like these give a bad name to business people with legitimate biz building skills.
Not really, the attraction of AeroFS is not having a connection/reliance on S3. So for something like 1Password syncing, it would be great not to have a copy sitting somewhere in the cloud.
There's a mental cost to each tool - small in the case of a hammer, a pliers, a screwdriver, a vicegrip, but much larger in the case of an IDE. IDEs with similar physical actions but different results have a much, much higher mental cost. Why do you suppose that "vim" people use "set -o vi" for bash command line editing?

Also, where's your "intuitive excuse"? You know, the one where someone is familiar with Windows at home, so we'll make them use Windows at the office because we don't have to retrain them? That sort of thing is more proof that multiple IDEs aren't the answer.
No floating point. I believe design complexity of the chip would increase manifold if it was. Emulation is not an option too with those extremely limited resources (64 words of memory). The design philosophy of this chip is that 18 bits of integer precision should be enough for your applications, period. I just feel like I'm not smart enough to figure out how to fit a useful application into that.
Oh, I didn't know that. I've just heard bad things about it.

Although I might be confusing this with the government business laws in France, which are also a bit messy. There's a reason lots of French companies have exactly 49 employees.
If something so simple is deemed optional, how many merchants do you think are going to be willing to pay to have the equipment to view your picture when they try to charge your phone.

Speaking of pictures associated with your phone. Where is this picture going to be stored? On the phone? Where, if someone steals it, they could replace it? Should we have a national database then that relates your phone number to an image of you?
This is certainly bad, assuming there's no "greater good" reason for the duplication, but it's merely contracting rather than scientific fraud, far less damaging to "science".

Old people with an iPad3 won't see the difference between a non retina and a retina website. They'll see which is the fastest and the easiest to use (because usually, pixel perfect guys are not too smart about UI.)

Retina-ready is a scam. We have neither the tools (SVG support too weak, no <picture> element, no good navigator.connection...) to provide a meaningful retina experience while respecting other users.
